3  Vorbereitung Übersicht / Preparation Overview

Preparing a computer-based assessment based on CBA ItemBuilder items begins with using the IRTlib Editor to create a study configuration. This typically involves the following steps:

  • Pre-requisite: Check the availability of the Runtime. The IRTlib Editor can be used to prepare assessments using CBA ItemBuilder Tasks. Using CBA ItemBuilder Tasks are stored in Project Files require a Runtime (i.e., the files “main..js” and “main..css”) in the version corresponding exactly to the version of the CBA ItemBuilder that was used to generate the items (e.g., 9.9.0). Before using the IRTLib editor, ensure the required Runtime is included or import the runtime files (see here for details).

Note: This step is usually not necessary for the use of CBA ItemBuilder items from version 9.9.

Note

Note that at least one study must be defined in the IRTlib Editor, before a study configuration can be used to collect data with an IRTlib Player.

Note

Note that each study neads at least one test-part defined in the IRTlib Editor, before a study configuration can be used to collect data with an IRTlib Player.
